The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X225-75 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 225mm stroke, G3/8 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.
The hard-anodized aluminum barrel keeps the assembly light without external tie rods.
The -75 code means an external adjuster lets you shorten the extend stroke on site by up to 75 mm, giving a usable range of 150-225 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. Air connects via a G3/8 port. Note this SKU lacks a magnet, so it cannot take CMSE or DMSE sensors.

Specifications follow the official AirTAC JSI (JIS standard) datasheet. Confirm against the product label before installation. Thread options: PT (blank) / G. Barrel: hard-anodized aluminum profile (no tie rods).
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 kgf | |
JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

|---|---|
| 63 | Bore size in mm (32 / 40 / 50 / 63 / 80 / 100 / 125). |
| ×225 | Stroke length in mm. |
| -S | Optional built-in magnet for CMSE / DMSE sensors. |
JSI-family variants: JSI (double acting), JSID (double rod), JSIJ (adjustable stroke). Mounting: LB / FA / FB / CA / CB / CR / TC / TCM1 / TCM2. Thread PT (blank) / G.
Dial in the exact 150-225 mm extend position for seating bearings without machining custom spacers.
Adjust the extend stop on site to deflect different carton sizes on a moving line.
Shift the extend end point by up to 75 mm to adapt to varying pallet depths.
The JSIJ mounting set includes Basic, FA, LB, TC, TCM1, and TCM2. The adjustable window is ideal when you need to tune end positions on site or want a shared spare across stroke variants. For any stroke at or over 300 mm, guide the load to prevent side-load wear. Without a -S suffix, this cylinder cannot accept magnetic switches.
Quick checklist
It pushes 1559 N and pulls 1402 N at 0.5 MPa. At 0.7 MPa it pushes 2182 N and pulls 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa. The air port is G3/8.
The nominal 225 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on site by up to 75 mm, yielding a usable range of 150-225 mm. The retract end is fixed. This stop only sets the end position; it does not hold the load on air loss.
